在几何问题中,要证明一条线段是另外几条线段的和差,或是另一线段的几倍或几分之几,我们统称为线段的和差倍分问题.处理这类问题的指导思想是化归为线段的相等问题.本文举例说明几种常见的求解策略.一、利用全等形或相似形对于线段的倍分问题,通常可利用图形中特殊的分点为解题的突破口,找出图形中 In geometric problems, to prove that a line segment is the sum of the difference between several other line segments, or a few times or a few of the other line segment, we collectively referred to as the line segment and the difference between the times to deal with. Is equal to the line segment equal to the problem.This article illustrates several common solution strategy.First, the use of congruent or similar shape for the times of the doubling problem, usually can use the graphics in a special point to solve the problem of breach, Find out in the graph
